The sun is on the verge of a significant event: a magnetic field reversal. What causes this switch in polarity, and is it dangerous for anything on Earth? Let's take a deep dive into the phenomenon of ...

Add Yahoo as a preferred source to see more of our stories on Google. Over 11 years of satellite data reveal that Earth’s magnetic field is reshaping. (CREDIT: Shutterstock) More than a decade of ...

You may have seen headlines or social media posts talking about a weakening of Earth’s magnetic field, specifically over the South Atlantic. It sounds dramatic, and a little scary. Is Earth losing its ...

Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory puts that timeline at roughly 5 to 10 billion years in galaxies. Yet ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

One particularly well-known fact about the moon is that it doesn't have much of a magnetosphere to speak of. There's no blanket to protect it from the solar wind ravaging its surface, blowing away its ...

Spacecraft reentry environments lead to high magnetic Reynolds numbers, resulting in complex dynamics for magnetic flow ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...
